[winswitch] XPRA/HTML5

Wed May 4 00:05:59 BST 2016

I managed to solve this and get it working.Somethings that I noticed :-
1. I needed to shut my apache server down for following to work :-
sudo xpra start --bind-tcp=0.0.0.0:80 --html=on --start-child=xterm

Couple of questions:- A) which web-server does XPRA start? B) Do I have a choice of sticking with Apache and still have this thing working ?

2. Following is faulty

sudo xpra start :10 --bind-tcp=0.0.0.0:80 --tcp-proxy=127.0.0.1:8000 --start-child=xterm

I could connect to xpra server using client application in TCP connection mode. But not from web-browser. Web-browser goes to the default index file and not to xterm.

One question -- How does user choose what he wants --- is he browsing to get to index file or is he trying to connect to xterm ?

Once again, thanks! Great product.

 Thanks!I have Apache webserver running on port 80. I have root access  but I need use port 80 for outside traffic for both the webserver and the xpra server because seems like firewall is blocking traffic on other ports.
I tried following :-
Editted /etc/apache2/ports.conf to make sure httpd is listening to 8080 and not 80.

Listen 8080
Then started apache :-
sudo service apache2 start

And then started xpra server on port 80 with "sudo"sudo xpra start --bind-tcp=0.0.0.0:80 --html=on --start-child=xterm

Will --html=on start a new web server? Or will it just start a porxy and point it to httpd listenning on 8080?

Otherwise, should I do following (again with "sudo") 

sudo xpra start :10 --bind-tcp=0.0.0.0:80 --tcp-proxy=127.0.0.1:8080 
--start-child=xterm

When I point the browser on the client machine on internet to http://SERVER-IP should I expect to see index page of webserver or the xpra xterm?

Last question, what does :10 mean here because seems like we are accessing xpra through tcp port 80. So why bother specifying display number? Where do I use :10 in the xpra attach command when using html5 client?

Thanks in advance! Help greatly appreciated.
